Scanner and method for encrypting/decrypting documents by using the scanner

Abstract

A method for encrypting/decrypting documents. The method includes the steps of: scanning a predetermined pattern; storing the predetermined pattern; scanning the documents; encrypting/decrypting the documents in accordance with the predetermined pattern.

1 . A method of encrypting/decrypting a document, comprising: 
 scanning a particular pattern;    storing the particular pattern;    scanning a document; and    encrypting/decrypting the document in accordance with the particular pattern.    
   
   
       2 . The method of encrypting/decrypting a document according to  claim 1 , wherein prior to the step of scanning the particular pattern, a step of scanning a compensating color panel is further comprised.  
   
   
       3 . The method of encrypting/decrypting a document according to  claim 1 , wherein prior to the step of scanning the particular pattern, a step of determining whether to encrypt/decrypt the document is further comprised: 
 if yes, performing the step of scanning the particular pattern;    else, scanning the document and ending the method of encrypting/decrypting a document.    
   
   
       4 . The method of encrypting/decrypting a document according to  claim 3 , wherein prior to the step of determining whether to encrypt/decrypt the document, a step of scanning a compensating color panel is further comprised.  
   
   
       5 . A method of authenticating a document, comprising: 
 scanning a particular pattern;    storing the particular pattern;    scanning a document; and    authenticating the document in accordance with the comparison between the particular pattern and the document.    
   
   
       6 . The method of authenticating a document according to  claim 5 , wherein prior to the step of scanning the particular pattern, a step of scanning a compensating color panel is further comprised.  
   
   
       7 . The method of authenticating a document according to  claim 5 , wherein prior to the step of scanning the particular pattern, a step of determining whether to authenticate the document is further comprised: 
 if yes, performing the step of scanning the particular pattern;    else, scanning the document and ending the method of authenticating a document.    
   
   
       8 . The method of authenticating a document according to  claim 7 , wherein prior to the step of determining whether to authenticate the document, a step of scanning a compensating color panel is further comprised.  
   
   
       9 . A method of activating a function of a scanner, comprising at lest the step of: 
 scanning a pattern;    storing the pattern; and    verifying the scanner in accordance with the pattern:    if verified, activating a function of the scanner.    
   
   
       10 . The method of activating a function of a scanner according to  claim 9 , wherein prior to the step of scanning the pattern, a step of scanning a compensating color panel is further comprised.  
   
   
       11 . The method of activating a function of a scanner according to  claim 9 , wherein prior to the step of scanning the pattern, a step of determining whether to activate the function of the scanner is further comprised: 
 if yes, performing the step of scanning the pattern;    else, scanning the document and ending the method of activating function of a scanner.    
   
   
       12 . The method of authenticating activating a function of a scanner according to  claim 11 , wherein prior to the step of determining whether to activate the function of the scanner, a step of scanning a compensating color panel is further comprised.  
   
   
       13 . A scanner, comprising: 
 a casing;    a scan module which is disposed inside the casing in a movable way; and    a pattern panel disposed on the casing;    wherein the scan module scans the pattern disposed on the particular pattern panel, and the pattern is for encrypting/decrypting a document during scanning or for activating a pre-set function of the scanner.    
   
   
       14 . The scanner according to  claim 13 , further comprises a compensating color panel for calibrating the scan module with, wherein the pattern panel is disposed adjacent to the compensating color panel.  
   
   
       15 . The scanner according to  claim 13 , wherein the pattern panel is disposed on the casing in a removable way.
